How to fix the error when I connect the E10A-USB emulator to the board?

Question:

When I connect the E10A-USB emulator to the board, I get the following messages: "Communication Timeout Error," "INVALID ASERAM FIRMWARE!," and "Error H-UDI boot." How can I fix this?

Answer:

Please confirm the following 8 items concerning the user system.

Was the number of H-UDI connectors counted correctly?

Is the wiring for the H-UDI connector correct?

Is there noise on any of the H-UDI connector signal lines?

Is reset is enabled for the device?

Is the Vcc value is correct?

Is the clock is oscillating?

If using E10A-USB, are pins ASEMD, DBGMD, EMLE, etc. set correctly? For details, refer to the following document for the target MCU: section 1.5 Pin Assignments of the H-UDI Port Connector in the E10A-USB Emulator Additional Document for Users Manual (for H8S and H8SX families, 1.4 Pin Assignments of the E10A-USB Connector).

Is the correct MCU operating mode selected? E10A-USB supported operating modes are listed in the E10A-USB Emulator Additional Document for Users Manual for each target MCU.

For SH2-DSP family E10A emulators, the reset vector (address H'A0000000) value is read at startup. If the reset vector cannot be read at setup due to a problem with the memory settings, the Link UP will not work.
